Default Curved top and base Tannoy Rect. GRF's come to life

After some exploits here
DIY Tannoy GRF's - Long with lots of pics

I got a request for audition and then make two pairs with curved tops.
First pairs is ready - I am very please with how the build went and the owner is very pleased with the GRF sound.

I have made the first pair for a Pink Fisher with Alnico 4 hole HPD's (later type crossover) and am about to start on a 2nd pair of earlier 8 hole mounting with the earlier Golds type crossover type for yet another Pink Fisher.

Here's one cab lot of wood all sanded and prepped.

24mm top, base and front. rest 21mm. These are going to have a nice weight to them

Back of the wardrobe. I make the backs removable so the bass can be tuned to suit different rooms. This is done with velco'd on felt sections - remove or fit to taste.
You do have to undo the 22 screws though.

All baffled and felted

Plinthed and castored

Well that's it so far for the first cab. Just the speaker posts, blind nuts, rear bracing, staining to taste and varnishing to go on this one.

And then there were two

On to final finishing / staining and grilles soon.

Got the Alnico drivers and crossovers today and mounted them up.

I also mock fitted the cloth (it's not stretched and stapled on) just to see how the full length grille fronts look with dark brown cloth from Wilmslow.

Oh yeah, here's a swatch of some colours to choose from - as many as Homebase, B&Q etc have also of course

Just got some great feedback both on finish and sound from the chap I made them for - makes it all worth it. He got them home safe and sound - phew they are rather heavy but fit in a Golf with the rear seats down.
He is staggered by the improvement over his Berkeley's. He has played them really loud to the point the Berkeley's would have broken down... Not these babies.
But it is normal listening vols where all the extra sub 200Hz mid and lower bass some out and make the music really special.
Comparisons with Ardens he has made are also very favourable for the Birch ply GRF's. The Ardens sound big and boomy but do not communicate the subtle mid and lower bass anything like as well.
Fun and games...
